Description

VIDEO TRANSCEIVER

BACKGROUND OF THE INVENTION

Videophones typically make use of Integrated Service Digital Network (ISDN) digital phone lines which have a broader bandwidth than analog telephone lines, i.e., Public Switching

Telephone Network (PSTN) phone lines. Communications over the ISDN digital phone lines are expensive, and they are not universally available.

With the advent of relatively fast modems, e.g., 28.8k bps modems, it has became increasingly desirable to send video as well as audio information over the PSTN analog phone lines. However, the use of videophones over the PSTN analog phone lines had many drawbacks.

First, because of the bandwidth limitation and lack of defined standard of video quality, the quality of the video was very poor. Second, because of a lack of standardization of communications protocol, manufacturers were producing videophone products that are not interoperable with each other, i.e., a videophone manufactured by one manufacturer was not able to communicate with another videophone manufactured by another manufacturer.

In order to allow for an interoperable, quality audiovisual communications over a PSTN analog phone line, the International Telecommunications Union (ITU) recently has adopted a new standard called H.324. The H.324 protocol, adopted by the ITU, is now the standard for audiovisual/multimedia communications over the PSTN analog phone lines. This new standard allows for interoperability and high quality video, voice, and data based phone calls. The H.324 standard makes possible a common method for the transmission of video, voice and data simultaneously over a high-speed modem connection.

Since the adoption of the H.324 standard, the desirability of products based on this new standard have become apparent. Some desirable applications of the new standard include video conferencing, remote video surveillance, security system monitoring and closed circuit television (CCTV). The standard also supports products which can be used in fire control and home automation applications. Other desirable applications include Internet browsing, electronic identification of fingerprints (EFI) and electronic handwriting recognition.

Those skilled in the art would understand the desirability ofhaving a product that provides the capability to perform all nine of the above listed functions in an integrated fashion. In addition, the current implementation of these desirable functions is cumbersome because a dedicated interface unit is not available. Therefore, those skilled in the art would understand the desirability ofhaving a self-contained video transceiver for multi-functional applications. This type of self contained video transceiver would necessarily provide automation applications including fire control, Internet browsing, electronic identification of fingerprints, and electronic handwriting recognition, thus providing these functions in an integrated unit. SUMMARY OF THE INVENTION

An embodiment of the present invention is directed to a video transceiver which satisfies this need. In one embodiment, a video transceiver includes a keypad for entering a telephone number, and a transceiver circuit capable of formatting a video input, an audio input and the entered telephone number for transmission on a PSTN telephone line. The transceiver circuit is also capable of extracting a PSTN telephone line input comprising a video signal, an audio signal and a telephone number identifying the video transceiver. Preferably, the video transceiver includes an indicator which indicates when the telephone number identifying the video transceiver is extracted by the video transceiver. In alternative embodiments of the present invention, the video transceiver is employed in numerous applications. By way of example, in one embodiment, a video transceiver having a keypad is coupled to a detector and an indicator which is responsive to the detector. The video transceiver includes a transceiver circuit which dials a telephone number in response to the detector, and couples an output of the detector to a PSTN telephone line. Preferably, an interface module is used to couple the detector and the indicator to the video transceiver.

A video camera output may also be coupled to the PSTN telephone line through the video transceiver in response to the detector and recorded by a video cassette recorder,

In an alternative embodiment, a video transceiver is coupled to the PSTN telephone line. The video transceiver includes a keypad and a transceiver circuit capable of extracting an appliance control signal from the PSTN telephone line. An appliance, responsive to the extracted appliance control signal, is coupled to the video transceiver. Preferably, an interface module is used to couple the video transceiver to the appliance.

In another embodiment, a video transceiver is coupled to the PSTN telephone line. The video transceiver includes a keypad and a transceiver circuit capable of extracting a number of appliance control signals from the PSTN telephone line. The appliances are preferably coupled to the video transceiver through an interface module, and are responsive to their respective extracted appliance control signals.

In yet another embodiment, a multiplex video transceiver is coupled to a number of keypad controllers. Each keypad controller is coupled to a video camera, a television monitor, a speaker, and a microphone. The multiplex video transceiver is coupled to a video transceiver having a keypad on a PSTN telephone line. Preferably, the video transceiver also includes a video camera, a television monitor, a speaker, and a microphone.

The described embodiments are multi-functional systems capable of performing video conferencing, remote video surveillance, security system monitoring, CCTV applications, fire control, home automation, Internet browsing, electronic identification of fingerprints and electronic handwriting recognition. The dedicated keypad of the video transceiver eliminates the need for using a telephone keypad for user control. Finally, the integration of a speaker and microphone into the video transceiver eliminates the need to rely on a telephone headset or a computer for voice communications. In other embodiments, the video transceiver may also be coupled to a handset.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 is a functional block diagram of a video transceiver 21 utilized in hand and portable applications. The transceiver is packaged to function as a home based unit, and alternatively, as a portable unit. The portable unit may be carried about and coupled to the PSTN via a hard wired modem connection or wireless connecti on via RF infrared signals. The video transceiver is used to transmit and receive audio 18 and video 16, 20 and data 14 signals over a Public Switching Telephone Network (PSTN). Those skilled in the art will appreciate that the video transceiver is capable of being adapted to work on telephone lines employing various signal transmission standards including ISDN, DSL and ADSL.

The video transceiver includes a keypad circuit 25 which provides a user interface to a transceiver circuit 21. The controller circuit 27 operates in cooperation with a multimedia processor circuit 23. The controller circuit 27 is responsible for managing overall operations of the video transceiver 21 and coordinating the flow of data 14, 16, 18 and 20 into and out of the system.

The controller circuit 27 preferably includes memory 24 for storing a directory of telephone numbers that are automatically dialed by the multimedia processor circuit 23 upon the occurrence of a certain event Alternatively, the controller circuit 27 commands the multimedia processor circuit 23 to dial a telephone number inputted by the user via the keypad circuit 25. The multimedia processor circuit 23 accepts commands from the controller circuit 27, processes video signals 16, 20, processes audio signals 1 and provides an interface to the PSTN telephone line through a modem connection 14. The multimedia processor circuit 23 accepts video 16, 20 and audio inputs 18 from external sources and in response to commands from the controller circuit 27, the multimedia processor circuit 23 formats the audio and video signals for delivery over a PSTN telephone line through a modem coupled to the modem in/out line 14.

The video input 16 is typically supplied by avideo camera providing a video camera signal having a standard video output such as NTSC or PAL. NTSC and PAL arc video standards well known in the art that specify line and field rates and include color information encoding. NTSC and PAL standards provide composite video signals having luminance and color information encoded in one signal. An NTSC compatible system operates with 525 lines per frame and 30 frames per second, A PAL compatible system operates with 625 lines per frame and 25 frames per second. In an alternative embodiment, the video signals 16, 20 are provided in a digital format. The audio input 18 typically comprises unmodulated voice or speech signals that vary in amplitude and frequency. Incoming signals on the PSTN telephone line received through the modem in out line 14 are separated into video and audio signals, processed, and delivered to the respective video 20 and audio outputs 18. The video output 20 is typically a standard video signal, such as PAL or NTSC, with sufficient drive for a television monitor. The audio output 1 is typically comprises voice or speech signals capable of driving an audio speaker. The controller circuit 27 also processes dedicated transmit and receive lines 32, 34. The transmit and receive lines are used to connect the controller circuit 27 to other modules 35 to increase functionality of the video transceiver. Exemplary modules include a home security module, automation module, and a fire control module.

FIG.2 illustrates a typically packaged home transceiver 35. In an embodiment, the video transceiver utilizes h gh density packaging and a light weight construction useful in both the home and portable applications. The home transceiver 35 is shown with an exterior housing 36 formed of a suitably sturdy material such as high impact plastic or metal. The home transceiver 35 includes an upward facing keypad 25. The housing 36 also incorporates four stands 38a, 38b, 38c, 38d to support the housing 36 above an operating surface such as a table or countertop. In an alternative embodiment, the four stands 38a, 38b, 38c, 38d are eliminated to enhance the portability of the home transceiver.

The keypad layout in other embodiments may be different For example, the keypad in other embodiments may have larger keys. The video transceiver may also include a remote handset 37 to be used during video conferencing. In an alternative embodiment, the portable video transceiver has a thin film transistor

(TFT) liquid crystal display (LCD) screen for the display of information being sent or received.

FIG.3 shows a portable video transceiver constructed to sit directly on a desktop or other operating surface. Exemplary dimensions of the housing are 8.7 inches long by 8.7 inches wide and 3.3 inches high. FIG.4illustratesatypi(^keypadkyoututUizei anembodimentofthetransceiver. The keypads in other embodiments may have different layouts. The keypad shown has ten alphanumeric keys as well as "*" and "#" keys which are typically utilized in many push-button type telephones. In addition, the keypad includes a function key "FUNC" 22, a dial key "DIAL" 24, an answer key "ANS" 26 and a clear key "CLR" 28. The integrated keypad eliminates the need to use a telephone or a computer keyboard as an input device.

The alphanumeric keys are used to enter user inputs such as telephone numbers and passwords. The FUNC key 22, the DIAL key 24, the ANS key 26 and the CLR key 28 are used to enter control command inputs. The FUNC key is used to establish communications and also to select different modes of operation. The DIAL key is pressed before entering a telephone number to initiate a call. The ANS key is used to answer a call. The CLR key is used to indicate the end of communications.

FIG. 5 is a system block diagram of the multimedia processor circuit 23. During the transmission of a locally generated video signal, that signal is routed to the video input 16 and is subsequently applied to the input of a video encoder/decoder 35 initial to the multimedia processor circuit 23. In alternative embodiments, the video encoder/decoder 35 is equipped with input multiplexing capability to allow video inputs from a number of video sources. The multiplexer 36 allows from 1 to any number "n" video signals to be sequentially coupled to the video input line 16. The video signal is amplified, filtered, and converted to a digital video signal 38 by the video encoder/decoder 35 by conventional methods known to those skilled in the art. The digital video signal 8 is then coupled to a video buffer circuit 31.

A video buffer circuit 31 manages the flow of the digital video signal into a digital signal processor (DSP) 33. The video interface buffer 43 provides temporary storage of the digital video. The video interface buffer utilizes conventional memory circuits known by those skilled in the art- Preferably, the video interface buffer 43 includes a dual port RAM configured such that both the controller circuit 27 (see FIG. 1) and the DSP circuit 33 can have access to the video interface buffer simultaneously. The output of the video buffer circuit 31 is coupled to a DSP 33. The DSP 33 provides data compression utilizing conventional compression circuitry known to those skilled in the art for data compression. The digital video signal presented to the DSP circuit 33 is compressed in accordance with a H.263 video compression format which is a new standardized format for transmitting video data over a PSTN telephone line. The H.263 video compression format is an International Telecommunications Union (ITU) standard for "Video Coding for Low Bit Rate Communication" and is well known to those with ordinary skill in the art.

The audio input 18, typically a speech or other audio signal, is applied to an audio coder- decoder (CODEC) 39. The audio CODEC 39 provides initial amplification and includes a bandpass filter designed to pass voice frequencies while limiting unwanted circuit noise. Typically, the bandpass filter (not shown) is designed to pass in-band signals having frequencies in the range of 300 Hz to 3400 Hz. The in-band signal from the bandpass filter is next converted to a digital audio signal in the audio CODEC 39 by conventional methods known by those skilled in the art and provided to the DSP circuit 33.

In the DSP circuit 33, the compressed digital video signals produced in it are integrated with the digital audio signals from the audio CODEC 39 into a format compatible with a H.324 protocol for transmitting and receiving audio and video data over the PSTN. Integration of the digital and video signals is accomplished with mixing circuitry known to those skilled in the art. This produces a formatted H.324 signal. A modem CODEC circuit 41 next processes the formatted H.324 signal. The formatted

H.324 compatible signals are then modulated by the modem coder-decoder (CODEC) circuit 41. The modulated formatted H.324 signal is then transmitted out of the modem CODEC circuit via the modem in out line 14. Preferably the modem used is a 33.6 kbps, V.34bis modem which is compatible with the H.324 format. Equivalently, any modem compliant with the H.324 format will perform satisfactorily.

During reception of a signal, the modem CODEC circuit 41 receives input signals over the PSTN through the modem in/out line 14. The input signals are demodulated, in a conventional manner known to those skilled in the art, and sent to the DSP circuit 33. The DSP circuit 33 extracts a digital video signal and a digital audio signal in a conventional manner known by those skilled in the art. The digital video signal, which is configured in the H.263 video compression format, is decompressed by the DSP circuit 33 in a conventional manner known by those skilled in the art

The video buffer circuit 31, under control of the DSP circuit 33, manages the flow of decompressed digital video from the DSP circuit 33 to the video encoder/decoder 35. The flow of decompressed digital video from the DSP circuit 33 to the video encoder/decoder 35 is facilitated by use of the video interface buffer 43 which provides temporary storage.

Next, the video encoder/decoder 35 further processes the decompressed video signal. The decompressed digital video signal is converted to an analog signal, amplified and filtered at the video encoder/decoder 35. In an alternative embodiment, a video demultiplexer 32 may is provided after the video encoder/decoder 35 to process a decompressed multiplexed digital video signal. The video output 20, which includes a number of demultiplexed video outputs in the alternative embodiment, is preferably routed to a television monitor compatible of processing a signal having a PAL or NTSC formatted signal or its equivalent. The DSP circuit 33 provides the digital audio signal 40, which has been extracted, to the audio CODEC circuit 39. The digital audio signal is converted in the CODEC 39 to an analog signal, filtered, amplified into an analog audio signal by conventional conversion filter and amplification circuitry known to those skilled in the art. The signal produced is suitable for driving an audio speaker at the audio CODEC output 18. The speaker compatible signal is outputted onto the audio in out line 18.

The described embodiment of the video transceiver is used in numerous apphcations. For example, audiovisual communication is established over a PSTN telephone line between two video transceivers. In an alternative embodiment, a computer or a telephone is used during such audiovisual communications. However, neither is required in the main embodiment. FIG. 6 shows in detail two video transceivers 51 A and 5 IB in a point-to-point communication system coupled by a PSTN telephone line 67. The video transceivers include keypads 63 A and 63B, respectively. The point-to-point communication system employs any number (n) of video transceiver systems 56A, 56B . . . 56n coupled via PSTN telephone lines. Those skilled in the art will appreciate that any number of transceivers may be connected to the

PSTN telephone to put multiple sites in communication with each other, for example, communications facilities video conferencing among a number of participants at various locations. The advantages of the video transceivers in audiovisual communications are realized by employing a number of peripheral devices. For example, in a preferred embodiment, each of two video transceivers 51 A and 51 B is connected respectively to a monitor 53 A, 53B, a video camera 55A, 55B, a microphone 57A, 57B, a speaker 59 A, 59B and an earpiece 61 A, 61B.

In an embodiment of the present invention, the microphones 57A, 57B and the speakers 59A, 59B are integrated into their respective video transceivers 51A, 51B. In another embodiment of the present invention, the microphones 57A, 57B and the speakers 59A, 5 B are standalone units.

In an embodiment, the monitors 53A, 53B are standard television sets. The video transceivers 51 A, 51 B have an adaptive video output for interfacing with a television set capable of processing any number of standard video signal formats, including PAL and NTSC.

The video cameras 55A, 55B are typically commercially available cameras having, for example, a PAL or NTSC video camera output. Equivalently, any other standard signal format may be used. In an embodiment, the video cameras have color CMOS or CCD image sensors 58A,58B in 1/4" to V?" format and generate composite NTSC/PAL or S-Video signals. A split screen configuration may be employed to handle a number video signals. By way of example, video transceiver 51 A could be configured with multiple video cameras which are multiplexed by the video transceiver 51 A, transmitted over the PSTN telephone line 67, and demultiplexed by the video transceiver 5 IB in a manner described above in connection with FIG. 5. The demultiplexed video signals from the video transceiver 5 IB could be connected to additional television monitors, or alternatively, formatted into a split screen configuration-

Those with ordinary skill in the art can appreciate that number of cameras that could be coupled to a single video transceiver can easily be varied. Moreover, additional video camera can be added by including additional input channels and modify internal circuits to handle the multiplexing of additional video signal inputs. Increased functionality can be achieved by utilizing a home security and automation module ("automation module") with the video transceiver. A simplified block diagram of the automation module is illustrated in FIG. 7A. FIG. 7B is a typical packaging of the automation module.

The automation module 115 includes a controller circuit 81 which has two pairs of dedicated transmit and receive lines 93, 95 and 97, 99 in addition to a video signal output 101. The controller circuit 81 also has bi-directional capability utilizing a RS-232 interface 103 which can be used to re-program the automation module 115 from a computer. The controller circuit 81 includes provisions to support three video cameras 83 A, 83B,

83C, three microphones 85A, 85B, 85C, three sensors 89 A, 89B, 89C and three home automation appliances 91 A, 9 IB, 91 C. In the described embodiment the viewing zones are shown in FIG. 7A with each zone having one video camera, one microphone, one sensor and one home automation appliance. The transmit and receive lines 97, 99 are used to connect the automation module 115 to another automation module or a fire control module. Therefore, the automation modules and fire control modules can be connected in series to a single video transceiver. The other transmit and receive lines 93 , 95 are for connection to the controller circuit 27 of the video transceiver (see FIG. 1 ) . The controller circuit of the video transceiver manages the flow of video and audio out of the automation module 115. By way of example, the controller circuit 115 includes a multiplexer (not shown) for multiplexing the video and audio from one of the zones in response to instructions from controller circuit 27 of the video transceiver.

FIG. 8 illustrates one application of the video transceiver with the automation module in a security control system. A burglar detector sensor 121 is used to detect an intrusion into a home. The automation module 115 receives an input from the burglar detector sensor 121 and activates a strobe light siren 113. At the same time, the automation module 115 monitors the surroundings with a video camera 119. The video camera output is coupled by the automation module 115 to a video recorder 123.

The burglar detection sensor output is coupled by the automation module to the video transceiver 117 which automatically dials one or more numbers to alert interested parties. A call can be made to a pager 128 to alert an owner of a home intrusion, or made to the owner's telephone 129 A. The call can also be placed to the owner's video transceiver 125A to allow direct viewing by the owner through a television monitor 127 A. If the owner is alerted over the telephone, the owner can use the video transceiver 125 A to monitor his or her home or property with the television monitor 127 A. If the owner is alerted over the video transceiver 125 A, the owner can monitor his or her home or property with the television monitor 127A simply by entering a password.

In response to the burglar detection output, the video transceiver 117 can also be programmed to alert police by dialing the telephone number for the police department 129B or a video transceiver 125B used by the police department. Similar to the owner, the police can monitor a home or property being burglarized by using the video transceiver 125B and the television monitor 127B. In order to gain access to the video transceiver 117, the police also need to know the password.

The owner of the home or property and the police can access the video transceiver 117 and monitor a burglary in progress at the same time. Control over the automation system can be given either to the owner or the police through a request sent to the video transceiver 117 over the PSTN telephone line 111. Once access to the automation system is acquired by either the owner or the police, commands can be entered into the keypad of his or her respective video transceiver. By way of example, if the owner gains control of the automation system, the owner may need to select one zone to view if his or her television monitor 127A lacks split screen capability. In that case, the owner enters the appropriate command on the keypad of his or her video transceiver 125 A. The command is sent over the PSTN telephone line to the video transceiver 117. The video transceiver causes the controller circuit in the automation module to multiplex the selected zone back to the transceiver for transmission over the PSTN telephone to the owner. Generally, once control is surrendered to one of the viewers, e.g., the owner, the other viewer merely becomes a passive viewer merely observing what is being transmitted over the PSTN telephone line. FIG. 9 illustrates another application of the video transceiver utilizing three automation modules 139, 141 and 143. A video transceiver 133 is coupled to a PSTN telephone line 131.

A video transceiver 135 and a telephone 137 are also coupled to the PSTN telephone line 131.

As illustrated in FIG. 7A and described earlier, each automation module can control up to three zones. Since the automation module can control only one home automation appliance in each zone, each automation module can control up to three home automation appliances. By connecting three automation modules in series, nine home appliances can be controlled. In the described embodiment, the automation module 143 controls a living room light 145, a garden fountain 153 and a garden sprinkler system 155. The automation module 141 controls an air conditioning unit 147 and a heater 157. The automation module 139 controls a cooking appliance 149, a television 159 and a garage door 1 1.

The automation modules 139, 141 and 143 are controlled by a user over the PSTN telephone line 131 from the telephone 137 or the video transceiver 135. In order for the user to control various home automation appliances, the user must know a password to access the video transceiver 133. First, the user dials the number for the video transceiver 133 from the telephone 137 or the video transceiver 135. Then the user enters the password, and then controls the home automation appliances by sending control commands to the automation modules.

FIG. 10A illustrates another application of the video transceiver utilizing a fire control module 162. As shown in FIG. 10, the structure and signals of the fire control module is similar to the structure and signals of the automation module illustrated in FIG. 7A. FIG. 1 OB is a typical packaging for the fire control module.

The fire control module includes a controller circuit 1 1 which has two pairs of dedicated transmit and receive lines 177, 179 and 181, 183 as well as a video signal output 185. The controller circuit 161 also has a capability for a bi-directional RS-232 interface 187 which can be used to re-program the automation module 162 from a computer. The controller circuit 161 also has capabilities for connections to three video cameras

163A, 163B and 163C, three microphones 165A, 165B and 165C, three speakers 167 A, 167B and 167C, three sensors 169A, 169B and 169C and three bells or sirens 171A, 171B and 171C. The controller circuit 161 also can be connected to up to six auxiliary devices with auxiliary outputs 173 A-C and 175 A-C. The connections for devices are organised into three zones A, B and C. The video camera 163 A, the microphone 165 A, the speaker 167 A, the sensor 169 A and the bell or siren 171 A as well as auxiliary outputs 173 A and 175 A would be in the zone A. Similarly, other devices and outputs would be organized into zones B and C. The transmit and receive lines 181 , 183 are used to connect the fire control module 162 to another fire control module or an automation module. The other transmit and receive lines 177, 179 are for ωrmection to the wntroUer circuit 27 of the video transceiver (see FIG. 1). The controller circuit of the video transceiver manages the flow of video and audio out of the fire control module 162. By way of example, the controller circuit 161 includes a multiplexer (not shown) for multiplexing the video and audio from one of the zones in response to instructions from controller circuit 27 of the video transceiver- The controller circuit 161 is used to process inputs and outputs of the fire control module.

FIG. 11 illustrates a fire control system with a fire control module 195 connected to a video transceiver 193. The video transceiver 193 is coupled to a PSTN telephone line 191. In case of a fire, the fire is detected by a fire detector 201. The fire detector output is coupled to the fire control module 195 causing a bell or siren 197, as well as a fire extinguishing system 199, to activate. The fire detector output is coupled from the fire control module 195 to the video transceiver 193. In response, the video transceiver 193 automatically dials the owner of a home or property where the fire has occurred at a video transceiver 207A over the PSTN telephone line 191, a telephone 211A or a pager 213. The video transceiver 193 also dials the fire station to access a video transceiver 207B or a telephone 21 IB. The access and control of the transceiver 193 by either the owner or the fire station is similar to the case of the security system based on an automation module as described above.

In an alternative embodiment of the present invention, an extension module is used to provide video camera expansion capability for the video transceiver. FIG. 12 illustrates a block diagram of an exemplary extension module. A video multiplexor 221 is used in the extension module to multiplex video signal inputs from video cameras. Four video cameras 225A-D provide the video signal inputs to the video multiplexer. Of course, those skilled in the art will appreciate that the actual number of video camera used can vary. A video signal output is generated by the video multiplexer of the extension module. The video extension module is connected to the video encoder/decoder 35 of multimedia processor circuit 23 of the video transceiver (see FIG. 5).

Another embodiment of the present invention is a video transceiver that can be controlled from remote locations with external keypad controllers. FIG. 13 is a preferred packaging of a multiplex video transceiver which is capable of being controlled from remote locations.

Turning to FIG. 14A, an alternative embodiment of the present invention is shown using a multiplex video transceiver. The multiplex video transceiver includes a transceiver circuit 240 comprising an audio/video circuit 243 coupled to a controller circuit 231. The controller circuit 231 is responsible for managing all operations of the multiplex video transceiver and coordinating the flow of data into and out of the system. The audio/video circuit 243 accepts commands from the controller 231 formats the data for transmission on a PSTN telephone line.

The multiplex video transceiver also includes a number of interface circuits. A video multiplexer circuit 233 provides a video camera interface to the controller circuit 231 of the transceiver circuit 240. The video multiplexer 233 receives a number of video camera inputs and provides a single video signal input to the controller circuit 231. A number of I O circuits 235 A-F provide an audio interface, as well as other peripheral interfaces, to the controller circuit 231 of the transceiver circuit 240. More particularly, each I/O circuit provides an interface between a two way audio communication line, a sensor input and an alarm output In the described embodiment, the controller circuit 231 communicates with six I O circuits, but the number of I/O circuits can vary.

The multiplex video transceiver also includes a keypad circuit 245 which provides a user interface to the transceiver circuit 240. An LCD display 247 is connected to the keypad circuit 245. The LCD display is used to display status messages. In particular, when a system check is run, results of the system check are displayed on the LCD display. In addition, the multiplex video transceiver has a capability for video in/out and keypad in/out interfaces for communicating with one keypad controller at a time. The keypad in/out interface includes an audio in/out interface. A power circuit 237 is connected to the controller circuit 231. The power circuit includes an AC/DC converter which allows DC power to be applied to the multiplex video transceiver by a conventional AC power outlet A DC battery 2 1 is connected in parallel to the output of the AC/DC converter 239 to maintain power in the event of an AC power failure. The power circuit 237 is also connected to a number of exterior connectors. As a result, peripheral devices such as video cameras can be simply plugged into the multiplex video transceiver to operate without an independent power source.

The audio/video circuit 243 is identical to the multimedia processor circuit of the home or portable video transceiver (see FIG.5). However, the interface between the controller circuit 231 and the audio/video circuit 243 is slightly different. In the multiplex video transceiver, all audio/video circuit 243 inputs and outputs are routed through the controller circuit 243. This is more a matter of convenience and one skilled in the art will readily appreciate that the inputs and outputs of the audio video circuit 243 could be coupled directly to the video sources, audio sources and the PSTN telephone line as described with respect to the home or portable video transceiver of FIG.5. By way of example, the controller circuit 231 provides a convenient mount for a telephone jack (not shown) for transmitting and receiving modem signals over a PSTN telephone line is connected to the controller circuit 231. Consequently, the output of the modem processor circuit 41 (see FIG. 5) is routed through the controller circuit 231. FIG. 14B is a video telephone conferencing system using one home transceiver 148, one portable transceiver 178, and one multiplex video transceiver 142. The video transceivers 142, 148 and 172 are coupled to each other over a PSTN 140. The home transceiver 148 and the portable transceiver 178 receive video camera outputs from video cameras 152 and 174, respectively, and displays to monitors 150 and 176, respectively. For the home and portable transceivers, audio communications are carried out through speakers 156, 168 and microphones

158, 172, respectively, or through earpieces 154 and 166, respectively, for hands-free operation.

A fire control module 144 and an automation module 146 provide additional capabilities for fire control and home automation/security system, respectively, to the multiplex video transceiver 142. However, the fire control module and the automation module can extend capabilities of the home transceiver 148 or the portable transceiver 178 as well.

The multiplex video transceiver is also connected to multiple input and output devices including sensors 180A-B, alarms 182A-B, video cameras 184A-B and call stations 188A-B. Even though two devices of each type are shown as example in FIG. 14B, the multiplex video transceiver has capabilities for handling many more input and output devices.

In a preferred embodiment of the present invention, the multiplex video transceiver can be connected to up to six keypad controllers simultaneously. In FIG. 14B, the multiplex video transceiver is connected to three keypad controllers 186A-C. From each of the remote locations associated with each keypad controller, audiovisual communication can be established with either the home transceiver or the portable transceiver through the multiplex video transceiver over the PSTN 140.

The three keypad controllers 186A-C receives video camera inputs from video cameras 192A-C, respectively, displays video signal outputs on monitors 194A-C, respectively, and establish bi-directional audio communications using earpieces 190A-C, respectively. Of course, the audio communications can be established using separate speakers and microphones instead of using the earpieces.

In a s stem with more than two video transceivers coupled together over a P STN as shown in FIG. 14B, a two-way audiovisual communication can be established between any two video transceivers. In addition, a three-way or a multi-way audiovisual communications can be established as well in a similar manner as athree-way or amulti-way telephone communications.

FIG. 15 is a preferred packaging of the keypad controller which includes a keypad and an

LCD display similar to the keypad on the multiplex video transceiver. In the preferred packaging, the keypad is a membrane keypad rather than a face plate with individual keys. A preferred packaging of the call box is illustrated in FIG. 16. The call box operates as a microphone and a speaker.

FIG. 17 is a system block diagram of a keypad controller. A video signal output from the keypad controller goes to a television while a video signal input from a video camera is received by the keypad controller and transmitted to the multiplex video transceiver. As shown in FIG. 17, video lines 251 and 253 are connected and interrupted using relays. For example, if the relay in the video line 251 is open, the television connected to the video line 251 does not receive any signals to display. Similarly, if the relay in the video line 253 is open, no video signal input from the connected video camera can be passed onto the multiplex video transceiver. Similar to the video lines, audio lines 255 and 257 can be opened or closed based on on/off status of relays. An audio output signal from the multiplex video transceiver passes through the relay in the audio line 255, is amplified by an audio amplifier 259, and transmitted to an earpiece. An audio input signal from the earpiece is amplified by an audio amplifier 261 and passes through the relay in the audio line 257, and then transmitted to the multiplex video transceiver. The audio lines 255 and 257 establish audio communications between the multiplex video transceiver and respective one of the remote control keypad controllers.

A keypad 263 of the keypad controller is used for entering user inputs which are provided to a keypad decoder 265. A keypad decoder 265 decodes user inputs made up of a series of alphanumeric and other keys. The decoded user inputs are transmitted to the multiplex video transceiver using a keypad interface circuit 267. In addition to driving the interface with the multiplex video transceiver, the keypad interface circuit drives an LCD display 269. Over the keypad in/out interface, the keypad controller remotely controls the multiplex video transceiver. The LCD display informs the user of the status of interface.

FIG. 18 is a flow diagram of how a caller initiates audiovisual communications with the video transceiver system over the PSTN. The caller picks up the handset as shown in step 271. Then the caller enters the phone number of the video transceiver to be accessed as shown in step 273.

When the call is picked up by a user on the other side as shown in step 275, the caller and the user can start video conferencing immediately. In one embodiment of the present invention, once the call is picked up, the user or the caller needs to press their respective video key as shown in step 277. Any time during video conferencing in step 279, either side can hang up by putting down the handset as indicated in step 281.

FIG. 19 is a flow diagram indicating how a call to the video transceiver over the PSTN is received. As a caller with a first video transceiver dials the number of a second video transceiver, when the incoming signal is received as shown in step 291 , a user on the side of the second video transceiver is alerted by a ringing sound similar to a telephone ringing as shown in step 293. The video transceiver then waits for the user to pickup the handset as shown in step 295.

Once the handset is picked up, the video transceiver waits for the video key to be pressed by either the caller or the user as indicated in step 297. In one embodiment of the present invention, a call is automatically answered if unanswered after a predetermined number of rings. In this case, the caller needs to enter a password to start audiovisual communications with the video transceiver at the user's end. Step 299 shows video conferencing between the second video transceiver and the first video transceiver. The communication can be for any of remote video surveillance, security system monitoring, closed circuit (CCTV) viewing, fire control monitoring or home automation applications. Once again, either side can hang up by putting down the handset as indicated in step 301.

FIG.20 is a flow diagram of a an exemplary operation of a security system which includes a video transceiver and a home security and automation module. Upon breaking in, a burglar is detected by a burglar detector sensor as shown in step 311, and the video transceiver receives warning per step 313. The video transceiver commands the home security and automation module to activate strobe light and siren, and the home security and automation module activates them as indicated in step 315.

Meanwhile, the video transceiver automatically calls and informs the police and the property owner of the intrusion as indicated in step 317. At the same time, the burglary is video taped as shown in FIG.319. The police or the property owner can call the video transceiver from another video transceiver and monitor and control the security system if they enter the correct password upon calling as indicated in steps 321, 323 and 325.

FIG. 21 is a flow diagram of an exemplary operation of a home automation system. To activate the home automation system, the user calls with a phone or a video transceiver as indicated in step 331. The home automation system checks for the input of a correct password as shown in step 333. Then the user enters commands and the video transceiver receives them to turn home appliances on or off as shown in steps 335 and 337.

FIG. 22 is a flow diagram of an exemplary operation of a fire control system using a fire control module and a video transceiver. The operation of the fire control system is similar to the operation of the security system illustrated in FIG.20. Steps 341, 343, 345, 347, 349, 351, 353 and 355 are similar to corresponding steps for the security system. A difference is that the fire control module detects fire with a fire detector sensor rather than burglary.

Accordingly, the present invention provides a remote surveillance and conferencing system for applications in the CCTV system, security systems, video conferencing, remote video surveillance, fire control and home automation. Although this invention has been described in certain specific embodiments, many additional modifications and variations would be apparent to those skilled in the ar It is therefore to be understood that this invention may be practiced otherwise than as specifically described.

FIG.29 is a flow diagram of an e-commerce transaction made over the Internet In order to make such a transaction, the customer typically utilizes a home transceiver as shown in FIG.23. As shown in FIG.23, an external module 2310 is coupled via the cable system 2306 to a transceiver unit 2302 and in turn to the public switched telephone network 2308 to enable the transaction to be made. The external module 2310 in an embodiment includes an electronic f geiprint identification (EFI) module for reading auser's fingerprint via the transceiver module 2302 and subsequently transferring it over the telephone wires 2308.

Returning to FIG. 29, a typical transaction utilizing electronic fingerprint identification starts with the user initiating the process 2902 through the transceiver unit (2302 of FIG. 23). At step 2904, the personal computer is turned on and the fingerprint collation application begins. At step 2906, the consumer selects goods, typically from a Web page displayed on a CRT display. The consumer typically utilizes the Web display to place these goods in a shopping cart or other equivalent means of selection on screen. At step 2908, a storekeeper coupled to the Internet sends the shopping information concerning the transaction being attempted by the consumer to a host computer. At step 2910, the consumer inputs his her credit card data into a personal computer.

At step 2912, the personal computer instructs the consumer to place his/her Internet commerce (IC) card on the personal computer. The IC card typically contains an electronic replication of the consumer's fingerprint .or equivalently a copy of the consumer's fingerprint. At step 2916, the personal computer reads the lϊr-gerprint data from the IC card and transfers the data to a fingerprint reader (FPR). Such a fingerprint reader is typically disposed in an electronic fingerprint module coupled to the transceiver previously described.

At step 1918, the consumer is requested to place his her finger on the fingerprint reader. At step 2920, the consumer places his/her finger on the FPR. At step 2922, the FPR collates the fingerprint data from the finger just placed on the reader against the fingerprint data contained in the IC card. At step 2924, the personal computer processes the result received from the fingerprint reader. If the FPR reading is acceptable, credit information from the IC card is read. At step 2926, credit data for the consumer is transferred to the personal computer. At step 2928, the transaction is complete.

FIG.30 is a block diagram of an e-comiuerce system. An e-commerce transaction system is illustrated in the block diagram that implements the transaction from the flowchart of FIG.29. The system includes a personal computer 2924 that is coupled to a fingerprint reader 2922 and also to a IC card reader 2918. The personal computer 2924, the IC card reader 2918 and the fingerprint reader 2922 typically are located near the user. A remote host computer 2924 processes the transaction.

The consumer makes the goods selection 2902 at the personal computer 2924, typically placing goods in an Internet shopping basket. Next, an Internet storekeeper or merchant sends the shopping information 2904 to a host computer 2924. Next, the merchant's credit data is transferred from the host computer to the personal computer 2906. A controller 2916 in the personal computer 2924 sends setup data to the fingerprint reader 2908. The customer places an

ICcard29l0 ontheICcardreader2918. The IC card reader reads fingerprint data in the IC card. The IC card reader then transfers credit data from the IC card to the personal computer 2926. The controller 291 in the personal computer 2924 sends IC card data read 2908 to the fingerprint reader 2922.

The controller in the personal computer 2924 deteπnines if the person whose fingerprint is being read has authorization to use the IC card they are attempting to make the transaction with. If the person using the IC card, as verified by the fingerprint reading, is authorized to make the transaction then credit card data is transferred 2914 from the personal computer 2924 to the host computer 2924.

FIG. 31 is a flowchart diagram of making a credit card transaction using electronic fingerprint identification. The credit card flowchart for a credit authorization terminal (CAT) implements a series of steps beginning with step 3102 where the process is initiated by a user.

At step 3104, the userplaces the IC card on a reader terminal. At step 3106, the reader terminal reads the fingerprint data in the IC card. At step 3108, the reader transfers finge rint data to a controller. At step 3110, the controller sends data from the IC card stored in the reader to a fingerprint reader module. At step 3112, tiie contioUer inquests the user to pla<»Ws/her finger on the FPR. At step

3114, the user places his/her finger on the fingerprint reader. At step 3116, the fingerprint reader collects the fingerprint data from the reading made by the FPR and compares it with the data collected from the IC card via the controller.

At step 3118, the fingerprint reader sends a result to the controller. The result comprises an okay (OK) or no good (NG) indication. At step 3120, the controller receives the result from the fingerprint reader and if OK, that is the fingerprints match the information on the IC card, the controller reads information from the IC card. At step 3122, identification data is sent to the host computer. At step 3124, the process ends. FIG. 32 is a block diagram of the hardware implementation of an e-commerce system utilizing electronic identification of fingerprints. In the embodiment shown, a controller 3224 coordinates the functioning of a IC card reader 3218 and a fingerprint reader 3222 coupled to the controller via two-way communication line. An IC card is placed on an IC card reader 3218, the IC card reader reads fingerprint data in the IC card and transfers 3212 the fingerprint data to the controller 3224.
